Sadly, popup window name is same as for vscode itself. I will have a look on that script, that's something to begin with. I use only one monitor at time, I don't use "extended mode". And what I really want - to transfer already opened applications to workspaces from different monitor: I have vscode opened on 4th workspace on laptop, after I plug in external monitor and setup xrandr for it, than I turn it off and want to continue working with vscode on 4th workspace on latop. Right now this is not possible from the box.

Yes.

It's easy way to learn things without fear to break something, can herbstluftwm use sxhkd?

Easily but why?

Sir, you are magician, addition to script did the trick!

Will definitely play with autorandr, because if I understood you correctly, it can automatically reload bspwm listening to certain events.

Right now I'm trying master (or understand, at least) QEMU, can you recommend me some combination with sane defaults (for ex mint + installer for herb) I can play on vm?

Thank you!

So I played around arandr and resolved initial issue...but got another one (as always). I added script to my bspwmrc file:

if [[ $(xrandr -q | grep "DP-1 disconnected") ]];
then
    xrandr --output eDP-1 --primary --mode 1920x1080 --pos 0x0 --rotate normal --output DP-1 --off --output HDMI-1 --off --output DP-2 --off --output HDMI-2 --off
    bspc monitor eDP-1 -d 1 2 3 4 5
else
    xrandr --output eDP-1 --off --output DP-1 --mode 1680x1050 --pos 0x0 --rotate normal --output HDMI-1 --off --output DP-2 --off --output HDMI-2 --off
    bspc monitor DP-1 -d  1 2 3 4 5
fi

So if i plug external monitor and reload bspwm (which also reloads polybar), it adds second pane to my polybar (1 2 3 4 5 1 2 3 4 5), but works.

Now smth interesting, when I unplug external monitor and then again reload bspwm, it switches to internal one but now cuts window for every application.

• Question 1: how to get rid of multiple workspaces on polybar when I toggle external monitor?
• Question 2: how to force bspwm respect resolution after switching resolutions?

I use dummy script to toggle monitors (from archwiki)

#!/bin/sh
intern=eDP-1
extern=DP-1

if xrandr | grep "$extern disconnected"; then
    xrandr --output "$extern" --off --output "$intern" --auto
else
    xrandr --output "$intern" --off --output "$extern" --auto
fi

Hm, never used arandr but it's similar to XFCE utlity on the first sight.

You setup profile where one display is enabled, another disabled, name him "external" and active in arandr every time connecting to external monitor, correct?

I turn of internal display and enable external by script, I don't use mirroring or extending

I also don't mirror, just switch from laptop to external and vice versa. Strange because lighdtm doesn't break anything for XFCE, quite interesting what is the reason

maybe I'm just one of very few that have external resolution lower than host

lightdm on both machines, any tips (besides installing xfce settings) how to achieve this scaling?:) strange, but I will try sddm
